I have no experience on a Ninja 250, so I can't comment on it, but I don't regret the Blast even for a moment. One thing that is nice about it but not mentioned, is a lot of the parts are the same as my Buell 1200. Simplifies tools and maintenance. I just love putting around town on it, so much easier to squeeze into tight spots than my 12, and once I picked it up and threw it over a median to make a Uturn in stopped traffic. (Ok more like carefully dragged it )
